Bush Bashing would be extremely popular and even profitable IF there was a solid argument. "Bush Lied" - "Bush oil" - "Bush cronies" - "War for oil" - and what ever they attempt to emphasize - are all very thin arguments. It's no small wonder that Air amerika failed.
Solid arguments are somewhat like a great song. You know what the next words are and you don't mind (and even enjoy) hearing them again.
The solid argument I most enjoy hearing is that President Bush knows the deep level of commitment that the Muslimes have towards pushing their beliefs and they aren't content to ignore those who disagree. Beheading is their default. It's simply a shame that a large percentage of the world's population seems to want to ignore this.
